MACHINE FOR TREATING PINEAPPLES.

SPECIFICATION forming part of Letters Patent No. 482,493, datedSeptember 13, 1892.

Application filed April 11, 1892. $e1'ialN0.428,582. (N0 model.)

To all whom it may concern;

3e it known that I, GEORGE W. ZASTROW, a citizen of the United States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements 1n Machines for Treating Pineapples,of which the following is a specification.

This invention relates to a machine for treating pineapples to preparethem for canning.

The object is to take the roughly-pared fruit and run it through amachine which will size, core, split, and slice it.

To this end the invention consists in the novel features of constructionand combinations of parts hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in which-Figure 1 shows a longitudinal section of the machine; Fig. 2, a sectionof a journal-bearing for the shaft of the rotary slicer; Fig. 3, across-section of the machine on the line 3 3 of Fig. 1. Fig. 4 shows afront view of the cylindrical cutter, the corer, and the splitter Withguard-plate attached. Fig. 5 shows a front View of the sliding carriagewith a cross- Fi 6 shows a detail side view of the corer an d splitterwith a projected end View thereof.

The letter A designates the bed-piece of the machine, which consists ofa hollow casting with a longitudinal slot A in its top and is supportedon suitable legs B. A carriage O rests on top of the bed-piece A and hasa guide-rib O fitting the slot A, which forms a slideway for it, andsaid carriage has a rack D fastened to said rib and contained within thebed-piece A. A pinion D engages said rack and is worked by a hand-wheelF. on its shaft. By this means the carriage may be reciprocated.

A circular head F is fastened on the front side of the carriage and hasa circular depression a. at the middle, and a cork screw G is fastenedin a suitable stem 11, which journals through the said head F and thecarriage and has a shoulder b fitting against the base of the depressiona. The corkscrew G projects from the face of the head F, and the stem Hcarries on the rear side of the carriage a crank-wheel I, by which itmay be revolved.

A standard J is stationed at a suitable place on the bed-piece A,andthis standard is formed with a stud K, which constitutes a bearingfor arotary cutter-head L, having the form of a pulley where it surrounds thestud K and provided With a part L, projecting beyond the said stud andshouldered to fit against the end of the same. This projecting part hasa cylindrical bore and receives a tube-section M, having a projectingcircular cutting-edge c. The head L is fitted over the stud K, against ashoulder (1, formed thereon, and is held on by means of a ring d, fittedagainst the opposite side of said shoulder and screwed to the head.Abrass bushing L is interposed between the rotary head L and the stud Kto take the wear. The standard J has a cylindrical bore extendingthrough it and lined with a bushing in the form of atube N, whose boreis in line with that of the tubesection M. v A coring-tube O is locatedconcentrically within the tube-section M and has a cuttingedge eprojecting a little beyond the circular cutting-edge c, and a radialblade P is fastened to the upper side of the coring tuloe O and extendsto the interior surface of the tubesection M. This blade presents aradial cutting-edge f, projected beyond the circular edge 0, and thesaid blade extends back through the tube N and has a widened part N, bywhich it is secured by bolts g to the standard J, engaging a slotprovided therein. The coring-tube O is cut away on the under side ashort distance back of its cutting-edge, so that from this point to itsrear end it is only partly tubular, as seen in Fig. 6.

The tube N extends to the rear end of the machine,where it is mountedinanother standard Q, fixed upon the bed-piece A, and between the twostandards J and Q a longitudinal slot 71. is made in the upper side ofthe tube to give access thereto.

A shaft R is mounted at one side of the machine in suitable bearings Rand carries a circular disk S on one end, said disk extending over theend of the tube N, with a suitable space between it and said tube. Thebearing at this end of the shaft is made with ribs 1', which engage inannular grooves j in the shaft to prevent longitudinal movement of thesame.

The disk S carries slanting knife-blades T on its inner side. In thepresent instance two of such blades are secured to the diskdiametrically opposite each other. Each blade has a strip or blockinterposed between it and the disk where it is fastened thereto, so thatthe blade will stand off from the face of the disk. The blade tapers inwidth, increasing toward the periphery of the disk, and has a roundedcutting-edgem. The blade is so set that said edge extends on an inclinetoward the periphery of the disk, as seen in Fig. 3, and will cross thetube N in such inclined position. Behind each blade a recess T is madein the disk, and this recess extends a little beyond the cutting-edge mand out to the periphery of the disk. At this peripheryof the disk italso extends back of the rear edge of the blade, as seen at- 0.

Power is applied to the rotary head L bya belt U, passing around thesame, and to the disk S by apply-inga belt to a pulley Von the end ofthe shaft R.

The operation is as follows: A pineapple \V,which has been roughlypared, is held in the hand against the corkscrew G and the crank Wheel Irevolved to enter said corkscrew into the core of the apple, and thushold the latter tightly up against the head F. Now the hand-wheel E willbe turned to move the carriage 0 toward the rotary cutter. The applethus moved upon the cutting-edges efc has an outside shell out from itby the revolving cutter M, While at the same time the tube 0 advancesthrough the center and cuts the core out and the blade P splits theapple radially from the cored-out center to one edge. The stationarysplitting-blade P holds the apple from turning. The circular head F hasa circular groove 0 in its face, into which the edge 0 may enter to cutthe apple clear and prevent dulling the said edge, and also a radialgroove f to receive the edge f. The coring-edge e enters the centraldepression a. The sized apple in cylindrical form enters the tube N,which forms aguideway for it, while the shell out from the exterior bythe circular edge 0 drops into a suitable receptacle below. A circularguardplate X extends around the rotary head L and is bolted to the baseof the standard J. This plate prevents the outside shell out by the edge0 from going past the projecting part L of the rotary head. The carriageG is moved back by turning the hand-wheel E in the opposite direction,and the core remains on the corkscrew G and may be removed therefrom inany suitable manner. Another apple is placed on the carriage and treatedlike the first one, and as this continues one apple shoves another alongin the tube N, as illustrated in dotted lines in Fig.

. 1. The farthest-advanced apple Y is pushed against the surface of thedisk S, and as the latter revolves the knife-edge in cuts a slice Y offthe apple. The action of the knife by reason of its peculiar shape andinclined position is to give a draw out in slicing, as the cutting edgeat the same time that it crosses the tube N draws downward, as bestillustrated in Fig. 3. The other blade acts in the same way, and hencetwo slices are cut from the apple with each revolution of the disk.After the blade cuts a slice the latter enters the recess T behind saidblade, and is thus freed, so that it may readily drop from the disk intoa receptacle placed below. The recess extends back, as at 0, to avoid awall against which the slice might strike and be thrown laterally fromthe disk. When the machine is to be stopped, the apples remaining in thetube Nare shoved through against the slicer-disk S by means of asuitable specially-prepared block inserted in the front end of the tubeand the last one or two by means of another blockinserted through thesloth in the upper side of the tube. The slices are delivered by themachine each with a radial split 2 in it. This facilitates theirintroduction into cans having contracted top openings.

It will be seen my machine sizes, cores, splits, and slices the apple,and this greatly expedites the handling of pineapples in preparing themfor canning.

The thickness of the slice may be varied by introducing liners behindthe knife-blades, so as to have them stand off farther from thedisk-face, and setting the disk at the proper corresponding adjustmenton the shaft.

It is evident that changes may be made in the construction andarrangement of parts without departing from the spirit and scope of theinvention.

Of course the machine may be employed for treating other articles thanpineapples.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
